Seasonal Patterns of Shark Activity in Scarborough
Spring and Early Summer Movements
During spring, water temperatures rise and bait fish migrate, drawing smaller shark species closer to shore. By early summer, blue and mako sharks become more common in waters used by swimmers and kayakers.
Peak Summer and Fall Observations
In July and August, increased fish schools lead to higher shark activity, including thresher sharks. Occasional white shark sightings appear in late summer when seals are most active near the coast.
Safety Guidelines and Beach Protocols
Swimmer and Boater Recommendations
Officials encourage swimming in monitored areas, avoiding dusk and dawn outings, and staying close to shore where depth is limited. Boaters are advised to keep trash secured and to avoid chumming.
Lifeguard and Town Response Plans
Scarborough Beach lifeguards use visual patrols, temporary closures when warranted, and clear signage. Town management coordinates with regional marine authorities to update guidance as sightings data evolves.
Local Marine Research and Tracking Efforts
Citizen Science and Sighting Reports
Fishermen, surfers, and divers contribute observations that help scientists map seasonal abundance. Standardized reporting forms make it easier to compare years and track changes in species frequency.
Acoustic and Satellite Monitoring
Receivers near popular fishing grounds and beaches capture tagged shark movements. This data supports public education and refines forecasts of when certain species are most likely to be present.
